The average annual sunshine time in Guangzhou is 1608 hours, which is correct.

The reason why the annual average sunshine time in Guangzhou is 1608 hours is related to its geographical location, climate characteristics, urban environment and many other factors.

Located in the south of China, Guangzhou belongs to the subtropical monsoon climate zone, with high temperature and rainy summer, mild and little rain in winter and four distinct seasons. This climatic feature determines that the sunshine time in Guangzhou is relatively long. In summer, the solar altitude angle is large and the sunshine time is long, while in winter, the solar altitude angle is small and the sunshine time is relatively short. In addition, Guangzhou's low latitude and high solar radiation intensity are also conducive to the increase of sunshine time.

Urban architecture, air pollution and other factors may also have an impact on sunshine time. With the continuous advancement of urbanization and the continuous rise of high-rise buildings, the shading effect on sunlight is becoming more and more obvious. In addition, air pollution will also increase the particulate matter in the air, affecting the penetration ability of sunlight, thus reducing the sunshine time.

Sunshine time will also be affected by many factors such as topography, season, weather conditions and so on. For example, in mountainous areas or seaside, sunshine time will be affected by terrain occlusion or seawater reflection; In rainy season or typhoon season, when the weather is gloomy and rainy, the sunshine time will be reduced accordingly.
